[0025] Figure 1 This is a schematic structural diagram of a COC chip testing device 100 according to an embodiment of the present invention. Figure 2 This is a schematic partial view of a COC chip testing device 100 according to an embodiment of the present invention. Figure 3 This is a schematic structural diagram of a tray mechanism 70 according to an embodiment of the present invention.

[0026] like Figures 1 to 3As shown, in a specific embodiment, the COC chip testing equipment 100 includes a loading mechanism 20, a testing mechanism 30, and a unloading mechanism 10. The testing mechanism 30 is used to test the COC chip. The loading mechanism 20 and the unloading mechanism 10 have the same structure and both include a material box 11, a gripper mechanism 60, and a tray mechanism 70. The material box 11 is used to hold a carrier plate 12. The carrier plate 12 has a mounting groove 122 for mounting a fishbone clamp 14, on which the COC chip is placed. The gripper mechanism 60 is used to clamp the carrier plate 12 and pull the carrier plate 12 out of the material box 11 or push the carrier plate 12 into the material box 11. The tray mechanism 70 is located at the outlet of the material box 11 and includes a first support platform 71, a first drive member 72, and a clamping assembly 73. When the gripper mechanism 60 pulls the carrier plate 12 out of the material box 11, one end of the material box 11 is gripped by the gripper mechanism 60, and the other end is located in the material box 11. The first drive member 72 drives the first support platform 71 to move upward to support the carrier plate 12; the clamping assembly 73 abuts against the side of the carrier plate 12, thereby clamping the carrier plate 12. When the fishbone clamp 14 is removed or placed on the carrier plate 12, the clamping assembly 73 releases the carrier plate 12, and after the first drive member 72 drives the first support platform 71 to move downward, the gripper mechanism 60 pushes the carrier plate 12 into the material box 11. Here, the carrier plate 12 has one or more mounting slots 122, that is, the carrier plate 12 can mount one or more fishbone clamps 14. The first drive member 72 is a cylinder.

[0027] This embodiment enables automatic loading and unloading of the fishbone clamp 14, improving the testing efficiency of COC chips and reducing labor costs. Furthermore, the design of the tray mechanism 70 allows for clamping of the carrier plate 12, enhancing the stability of the fishbone clamp 14 during material handling.

[0028] In some embodiments, the material box 11 is automatically placed on the loading mechanism 20 or the unloading mechanism 10 by an automatic transport trolley, and the automatic transport trolley can also automatically remove the material box 11 from the testing equipment 100.

[0029] In some embodiments, the top of the first support platform 71 is provided with a groove, and when the first support platform 71 supports the carrier plate 12, the carrier plate 12 is located in the groove. The clamping assembly 73 includes a second drive member 731 and a connecting plate 732. The connecting plate 732 is connected to the first support platform 71, and the second drive member 731 is mounted on the connecting plate 732 and configured to push the carrier plate 12 from a first side, such that the second side of the carrier plate 12 abuts against the side wall of the groove. Here, the carrier plate 12 has a first end and a second end. After the clamping assembly 73 clamps the first end of the carrier plate 12 and pulls the carrier plate 12 out of the material box 11, the second end of the carrier plate 12 is located in the material box 11. At this time, the first end and the second end of the carrier plate 12 are supported, but the middle part of the carrier plate 12 is not supported. Then the first drive member 72 drives the first support platform 71 to move upward, thereby supporting the middle part of the carrier plate 12. As the first support platform 71 moves upward, the clamping assembly 73 moves accordingly. Then, the second drive member 731 presses against the carrier plate 12, thereby supporting and limiting the carrier plate 12. Here, the second drive member 731 is a cylinder. The piston rod of the cylinder extends out and presses against the first side of the carrier plate 12, pushing the carrier plate 12, thereby clamping the carrier plate 12 in the slide groove.

[0030] Figure 4 This is a schematic structural diagram of the third driving member 75 according to an embodiment of the present invention. Figure 5 This is a schematic structural diagram of the fourth driving member 77 according to an embodiment of the present invention. Figure 4 and Figure 5 As shown, in some embodiments, the fishbone clamp 14 has a first positioning hole 141. The tray mechanism 70 also includes a third drive member 75 and a first positioning post 76. The third drive member 75 is mounted on the bottom of the first support platform 71 and moves with the first support platform 71. The first positioning post 76 is connected to the third drive member 75, and the third drive member 75 is configured to drive the first positioning post 76 upward, so that the first positioning post 76 passes through the first positioning hole 141, thereby positioning the fishbone clamp 14. Here, the third drive member 75 is a cylinder.

[0031] In some embodiments, the carrier plate 12 has a second positioning hole 121. The tray mechanism 70 further includes a fourth drive member 77 and a second positioning post 78. The fourth drive member 77 is mounted on the bottom of the first support platform 71 and moves with the first support platform 71. The second positioning post 78 is connected to the fourth drive member 77, and the fourth drive member 77 is configured to drive the second positioning post 78 upward, so that the second positioning post 78 passes through the second positioning hole 121, thereby positioning the carrier plate 12. Here, the fourth drive member 77 is a cylinder.

[0032] In some embodiments, the tray mechanism 70 includes a bracket 79 connected to a first drive member 72. A first support platform 71 is mounted on the bracket 79, a connecting plate 732 is connected to the bracket 79, and both a third drive member 75 and a fourth drive member 77 are connected to the bracket 79. It can be understood that when the first drive member 72 drives the bracket 79 to move up and down, it can simultaneously drive the first support platform 71, the second drive member 731, the third drive member 75, and the fourth drive member 77 to move up and down.

[0033] Figure 6 This is a schematic structural diagram of a gripper mechanism 60 according to an embodiment of the present invention. Figure 6 As shown, in some embodiments, the gripper mechanism 60 includes a fourth guide rail 6141 and a gripper 62. The fourth guide rail 6141 is arranged along the front-rear direction of the testing equipment 100, and the gripper 62 is slidably mounted on the fourth guide rail 6141, thereby enabling the carrier plate 12 to be pulled out of the material box 11 or pushed into the material box 11.

[0034] In some embodiments, the testing equipment 100 further includes a first guide rail 53 and a conveying mechanism 50. The first guide rail 53 is arranged along a first horizontal direction, and the loading mechanism 20 and the unloading mechanism 10 are respectively arranged at both ends of the first guide rail 53. The conveying mechanism 50 is slidably mounted on the first guide rail 53 and is used to remove the fishbone clamp 14 from the carrier plate 12 or place the fishbone clamp 14 on the carrier plate 12. Here, when the COC chip has completed testing, the carrier plate 12 of the tray mechanism 70 corresponding to the unloading mechanism 10 is empty, that is, the carrier plate 12 is not placed on the carrier plate 14. The conveying mechanism 50 needs to move the fishbone clamp 14 to the carrier plate 12 of the tray mechanism 70 corresponding to the unloading mechanism 10, where the tested COC chip is placed on the fishbone clamp 14. When COC chips need to be tested, the tray mechanism 70 corresponding to the feeding mechanism 20 has a fishbone clamp 14 on its carrier plate 12. The fishbone clamp 14 holds the COC chip to be tested. Then the conveying mechanism 50 removes the fishbone clamp 14 to perform LIV and spectral tests on the COC chip.

[0035] In some embodiments, the carrier plate 12 has a first mounting groove and a second mounting groove, and the number of fishbone clamps 14 is two, defined as a first fishbone clamp and a second fishbone clamp, with the first fishbone clamp corresponding to the first mounting groove and the second fishbone clamp corresponding to the second mounting groove. The first support platform 71 has a material pick-and-place position 74.

[0036] When loading COC chips, the gripper mechanism 60 pulls the carrier plate 12 out of the material box 11, positioning the first mounting slot at the pick-and-place position 74. The conveying mechanism 50 then removes the first herringbone clamp from the first mounting slot. Afterward, the gripper mechanism 60 controllably pulls the carrier plate 12, positioning the second mounting slot at the pick-and-place position 74, and the conveying mechanism 50 removes the second herringbone clamp from the second mounting slot. Here, the tray mechanism 70 also includes a fifth drive member 791 and a second support platform 792. After the gripper mechanism 60 controllably pulls the carrier plate 12, positioning the second mounting slot at the pick-and-place position 74, the fifth drive member 791 drives the second support platform 792 upward to support the carrier plate 12. The structure of the fifth drive member 791 is the same as that of the first drive member 72, and the structure of the second support platform 792 is the same as that of the first support platform 71.

[0037] During the unloading of COC chips, the gripper mechanism 60 pulls the carrier plate 12 out of the material box 11, positioning the second mounting slot at the pick-and-place position 74. The conveying mechanism 50 places the second herringbone clamp into the second mounting slot. Then, the gripper mechanism 60 controllably pushes the carrier plate 12, positioning the first mounting slot at the pick-and-place position 74. The conveying mechanism 50 places the first herringbone clamp into the first mounting slot. Finally, the gripper mechanism 60 pushes the carrier plate 12 into the material box 11. After the conveying mechanism 50 places the second herringbone clamp into the second mounting slot, the fifth drive member 791 drives the second support platform 792 downwards to release the carrier plate 12. Then, the gripper mechanism 60 controllably pushes the carrier plate 12, positioning the first mounting slot at the pick-and-place position 74.

[0038] Here, the carrier plate 12 is provided with two second positioning holes 121, which correspond to the first fishbone clamp 14 and the second fishbone clamp 14, respectively. It should be noted that before the gripper 62 needs to move the carrier plate 12, the first positioning post 76 needs to disengage from the fishbone clamp 14, and the second positioning post 78 needs to disengage from the carrier plate 12.

[0039] Figure 7 This is a schematic structural diagram of a testing mechanism 30 according to an embodiment of the present invention. Figure 7As shown, in some embodiments, the test device 100 further includes at least one test mechanism 30, each test mechanism 30 including a test stage 34, a pressing assembly 33, and a photodetector 42. The test stage 34 is used to place the fishbone clamp 14, and the conveying mechanism 50 is configured to place the fishbone clamp 14 on the test stage 34 or remove the fishbone clamp 14 from the test stage 34. The pressing assembly 33 is located above the test stage 34 and includes a test probe. When the fishbone clamp 14 is located on the test stage 34, the pressing assembly 33 is pressed down in a controlled manner, so that the test probe communicates with the COC chip on the fishbone clamp 14, thereby obtaining the test signal of the COC chip. The photodetector 42 is installed on the side of the test stage 34 and is used to detect the light intensity signal emitted by the COC chip. Here, the fishbone clamp 14 is provided with a substrate, the COC chip is mounted on the substrate, and the test probe contacts the substrate, thereby achieving communication with the COC chip. After the test probe contacts the substrate, it applies current or voltage to the COC chip. The front end of the COC chip emits light, and the photodetector 42 collects the light and detects the light intensity of the COC chip.

[0040] In some embodiments, the fishbone clamp 14 has two rows of mounting positions, meaning that two rows of COC chips can be mounted. There are two photodetectors 42, arranged opposite each other, each used to detect the light emitted by one row of COC chips.

[0041] In some embodiments, the fishbone clamp 14 is in a first state arranged along a first horizontal direction when it is on the carrier plate 12, and in a second state arranged along a second horizontal direction when it is on the test stage 34. The conveying mechanism 50 includes a rotating component 51 and an adsorption component 52. The adsorption component 52 is used to adsorb the fishbone clamp 14. The rotating component 51 is connected to the adsorption component 52 and can drive the adsorption component 52 to rotate, thereby causing the fishbone clamp 14 to switch between the first state and the second state.

[0042] The conveying mechanism 50 of this embodiment can change the direction of the fishbone clamp 14, which means that the fishbone clamp 14 is arranged along the first horizontal direction in the feeding mechanism 20 and the unloading mechanism 10, and along the second horizontal direction in the testing mechanism 30. This design can make the structure of the testing equipment 100 more compact.

[0043] In some embodiments, the testing device 100 further includes a second guide rail 31, a third guide rail 41, and a test platform 43. The second guide rail 31 is arranged parallel to the first guide rail 53, and the crimping assembly 33 is slidably mounted on the second guide rail 31. The third guide rail 41 is arranged parallel to the second guide rail 31, and the photodetector 42 is slidably mounted on the third guide rail 41. The test platform 43 is mounted on one side of the test platform 34 and is used to place the fishbone clamp 14, which holds the chip sample. The crimping assembly 33 is also configured to move along the second guide rail 31 to a position above the test platform 43 and to press down in a controlled manner, so that the test probe communicates with the chip sample, thereby obtaining the test signal of the chip sample. The photodetector 42 is configured to move along the third guide rail 41 to a position opposite to the test platform 43, and is used to detect the light intensity signal emitted by the chip sample, so as to determine whether there is an abnormality in the testing device 100 based on the test signal and light intensity signal of the chip sample. Here, the test equipment 100 also includes a fourth guide rail 32, which is arranged vertically. The crimping assembly 33 is slidably mounted on the fourth guide rail 32 and can move up and down. The fourth guide rail 32 is slidably mounted on the second guide rail 31.

[0044] This embodiment can alert maintenance personnel to repair the test equipment 100 when there is an abnormality, and directly test the COC chip when there is no abnormality, thereby ensuring that the test equipment 100 can operate normally.

[0045] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
